Claims (5)

  1. Circuit pour la limitation du courant d'appel d'un transformateur (1) avec un contacteur (5), sur les entrées duquel la tension de service (4) du transformateur (1) est appliquée et dont les sorties sont raccordées aux bobinages primaires (2) du transformateur (1),
    avec des résistances ohmiques (10) couplées en série et des conducteurs à froid (11) couplés en parallèle au contacteur (5), caractérisé par
    un bobinage de contrôle (14) du côté secondaire (3) du transformateur (1) ayant au moins deux connexions (16, 17), étant couplé à une résistance supplémentaire (12), la résistance supplémentaire (12) étant connectée entre
    une première connexion (16) du bobinage de contrôle (14) et l'entrée d'alimentation (7) du contacteur (5), et
    la sortie d'alimentation (8) du contacteur étant raccordée à une seconde connexion (17) du bobinage de contrôle (4),
    le contacteur (5) se fermant et court-circuitant les résistances ohmiques (10) couplées en série et les conducteurs à froid (11) lorsque la tension induite dans le bobinage de contrôle (4) et appliquée à l'entrée d'alimentation (7) et à la sortie d'alimentation (8) dépasse le seuil de commutation du contacteur (5).
  2. Circuit selon la revendication 1,
    le bobinage de contrôle (14) étant un bobinage secondaire sélectionné.
  3. Circuit selon la revendication 1 ou 2,
    caractérisé en ce que
    un redresseur (15) est couplé entre les sorties (16, 17) du bobinage de contrôle (14) et la résistance supplémentaire (12).
  4. Circuit selon la revendication 1 ou 2,
    caractérisé en ce que
    le bobinage de contrôle (14) est formée comme bobinage monophasé.
  5. Circuit selon l'une des revendications 1 à 4,
    caractérisé par
    un contact auxiliaire (13) dans le contacteur, qui est couplé en parallèle à la résistance supplémentaire (12) et est raccordé aux commutateurs (6) du contacteur de telle manière que le contact auxiliaire (13) est fermé lorsque le commutateur est en position ouverte et vice versa.
